METHOD OF PRODUCING HIGHLY CONCETRATED SOLUTION OF MINERAL FERTILISER FOR SEED PRESOWING TREATMENT

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to agriculture. Aqueous solution of mineral fertiliser for seed presowing treatment based on macro- and micro-elements with a disodium salt of ethylenediaminetetraacetic acid is prepared by mixing solutions which are diluted with water. Solution No. 1 contains salts in the following concentration: phosphorus mineral salts (P2O5) 0.68-1.0%; potassium (in form of K2O) 6.2-10.7%; boron 0.27-1.013%; selenium 0.016-0.030%; molybdenum 0.26-1.09%; vanadium 0.038-0.152%; chromium 0.037-0.154%; and solution No. 2 contains salts in the following concentration: copper 2.657-3.875%; zinc 2.769-3.461%; magnesium 1.200-1.407%; iron (III) 0.198-0.521%; cobalt 0.128-0.365%; nickel 0.018-0.09%; lithium 0.047-0.142%; manganese 0.278-0.377%. ^ EFFECT: improved application properties of the composition for treating seeds by obtaining a highly-concentrated solution having balanced micro- and macro-elements. ^ 4 cl, 4 ex
